I'm trying to use build a amqp uri with camel, follow the
camel official document for amqp:
On the documents I found the uri for amqp ls like amqp:destinationType:destinationName.
I don't find any parameter for exchange and routingKey. How could I add these parameters to amqp uri?
I have tried amqp:destinationType:destinationName?exchangeName=aaa&routingKey&routingKey=bbb, but not works.
Thanks if any help!

According to apache camel document
useSystemProperties could be used as query param for http component like below shown
https://URL ?useSystemProperties=true
But I want to use do it via API(method) way. Is it possible and how?
Thanks in advance
I use Apache Camel 2.20x.
A camel component can be developed with a uri scheme for example "sample-component". Now the Endpoint of this component can actually extend an existing Endpoint say SQL which has uri syntax as "sql:<select query">.
Now I am listening to camel Exchange event (ExchangeSentEvent) When I retrive the uri from the event I get "sql:<select query">. But what I want is to get "sample-component". How can we achieve that. In simple terms following is the ask
How can we get all Endpoint uri schemes for a camel component.
Thanks in advance
Gk
ComponentName+Endpoint . You can see all the uri that the component will take. All camel components are named this way.There may be exceptions. also if u use intellij idea apache camel plugin it show .
examples
HttpEndpoint
TimerEndpoint
SedaEndpoint
DirectEndpoint
You can also find the consumer and producer classes of these components as follows.
HtppProducer if support HttpConsumer ..
Actually I am playing with apache-camel 2.15.2, the REST DSL available since Camel 2.14 is not complicated. However I can't find in the official documentation how to retrieve a query parameter, basically I would like to target my REST service in this way:
http://myServer/myService/myMethod?myQueryParam=myValue
Is that possible, or is there any workaround ?
Thanks in advance.
Camel uses the REST/HTTP component of choice (restlet, jetty, servlet, netty-http, spark-rest, etc) which maps query parameters as Camel message headers.
So yes you can with the rest-dsl exposes a REST service where clients can call it with query parameters, which is then mapped to Camel message headers during routing.
I was looking up online how to create a Camel's CXF producer (i.e. create a CXF endpoint that would produce a request to some local/remote web service). Generally, all the examples I could find would list the following steps:
First define the cxfEndpoint attributes:
<cxf:cxfEndpoint
id="orderEndpoint"
address="http://localhost:9000/order/"
serviceClass="camelinaction.order.OrderEndpoint"/>
Then send the request to that endpoint:
...to("cxf:bean:orderEndpoint");
Hmmm. I don't understand the concept. If this is a remote web service, all I usually have is the URL of the WSDL. I can get from it the address of the service... but I don't know what the serviceClass is and I don't have it on my classpath.
So how do I define that cxfEndpoint in case I only have the URL of the WSDL?
Or is there another type of endpoint I should use in that case?
I would suggest looking into WSDL first for cxf. Below are two links that I think should help you out quite a lot and has helped me in the past as well.

On the Red Hat site you will need to start at chapter 3.
Hope this helps.
I have a camel route setup like the following to send a java object to an activemq queue.
from("direct:clientRequest")
.marshal().json(JsonLibrary.Jackson)
.to("activemq:queue:command");
I want to do the following:
Map the "clientRequest" uri to some Java method
Use ProducerTemplate's "sendBody" method to send a JSON form of a Java object to the activemq queue.
Is this possible?
I am asking this question after a lot of homework. Please suggest a way to do this.
You can use pojo producing in Apache Camel. See this page for more details
http://camel.apache.org/pojo-producing.html
And there is an example that shows more about using pojo producing/consuming in Camel
